Jack's trousers and everything else below knee level were now out of sight, out of mind. Understanding what Jack wanted when he guided his hand, Ianto still couldn't refrain himself from deeply squeezing the delicate flesh of his lover's inner thigh. Brushing it higher, he curled his fingers around Jack's unrestrained length, and he delighted in the bare flesh as though it was gold. Seduction hadn't been on his mind when he'd arrived there. It hadn't been on his mind when he'd walked into the office. But Jack's touch and the feel of him so easily provoked feelings Ianto had rarely (if ever) experienced before he'd known the captain, and he loved it.
His knees squeezed Jack's hips of their own volition, displaying his growing frustration that his trousers were still in tact, albeit loosened now, which was a bit of relief. It wouldn't be easy to wriggle out of his material trappings, and even if he managed to work the angle, he wouldn't look half as good as Jack in the process. So he didn't try, just yet.
"Just don't choose now to change any positions," he breathed; the fluidity of his speech was wavering, and the moan that was working its way up from his throat was audible in his voice. With his firm strokes of Jack, he could feel him hard, so hard in his grip, and it was sending tremors up his spine. His tongue darted out to lick his own lip.
Oh, to hell with it. Releasing Jack carefully, Ianto fumbled his thumbs into the sides of his waistband and, gripping the loose material, he shoved his shoulders against the wooden surface, causing his back - and by extension, his hips - to arch. Pulling both his trousers and boxers down quickly, he relaxed his thighs onto the surface again. If Ianto had been able to read minds, he would have found his own gratitude for the stability of the desk echoing right there alongside Jack's. Especially when one considered - judging by their current placement - the most likely place splinters would end up, and Ianto would not be happy explaining that one to Owen when he had to have them medically extracted.
